Increasing safety
should be a smooth ride.

You could say it’s the road less travelled; gathering road surface information completely without cameras. But with advanced sensor fusion, RSI by NIRA makes it a very real possibility – enabling greater comfort and safety in a truly cost-efficient manner. Sounds good? Then imagine the possibilities when sharing road information in a connected vehicle cloud.

Roads vary in terms of surface structure and quality, and the road surface affects both tire wear and ride comfort. In addition, roads with potholes pose a direct safety risk, where an impact could initiate structural tire damage – later leading to a tire blow out.

The solution? Road Surface Information, RSI by NIRA.

Unlike other systems using cameras or sensors in the air suspension, RSI by NIRA is a sensor-less solution for indicating the road surface condition. Utilizing signals from existing automotive grade sensors, such as the wheel speed, RSI can determine the road roughness in six levels. It can also detect speed bumps and make a damage assessment of a possible pothole impact, storing the event in a non-volatile memory and alerting the driver if necessary. While RSI is an obvious safety feature, it’s just as much about increasing driver comfort, as it enables adaptive suspension setting in real-time.
